In the accompanying drawing Figure 1 is a plan view of my improved machine; Fig. 2- is a cross section thereof; Fig. 3- is an elevation thereof; Fig. 4 is a cross sectional elevation thereof; Fig. 5 is a rear elevation thereof; Fig. 6 is a view of a bottle carrying crate in connection therewith, and Fig. 7- is a detail view of an adjustable sleeve in connection therewith.

Similar figures refer to similar parts throughout the several views.

On a base 1 provided with threaded holes 2, for bolts 3, for fastening the base, is mounted a gear chest 4. Between the top 5 of the base 1 and the bottom 7 of the chest 4 is a reservoir 6. The reservoir 6 is fed by a water pipe 10. The bottom 7 of the chest 4 is provided with a number of threaded taps 12 preferably sixteen for the threaded ends 13, under nuts 8 of nozzles 15. Over nozzles 15 are revolubly mounted tubular journals 16 which are revolubly supported by vertical bearings 17, in a bottom 18 of a trough 9, provided with pedestals 19, 19' and mounted on top of chest 4. The pedestal 19 is provided with a bearing 20 for a journal 21, of a power shaft 22, and the pedestal 19 is provided with a bearing 20 for a journal 21' of said shaft 22. On the shaft 22 at the bearing 20 as at 24 is fixedly mounted a bevel gear 25 meshing with a follower 26 mounted on a vertical transmitter shaft 27 revolvingly supported bya bearing 28 in the pedestal trough 9 and by a bearing 29 in the bottom 7 of the chest 4.

On the vertical shaft 27 is fixedly mounted a large spur gear 30, driving a train 31 of gears fixedly mounted on the tubular journals 16. The train of gears 31 consists of the short gears A and B, one below the other, meshing with the gear 30. The gear A meshes with a gear C and the gear B meshes with a gear D, but A and B do not mesh. Gear A meshes with a gear A which meshes with a gear A" meshing with a gear A. B meshes with B which meshes with B" meshing with B O meshes with C which meshes with C" meshing with C', and D meshes with D which meshes with D" meshing with D" On the tubular journals 16 are tapped tubular washers 14 consisting of spindles 32, provided with spouts 33 and with brushes 34.

The base 1 is provided with a vertical socket 35 for the lower end of a cylindrical post 36 and fastened therein by a bolt 37. The post 36 is provided with a horizontal hole 38 forming a bearing for a driven shaft 39, provided with a journal 40, for a bearing 41 in the journal 21' of the power shaft 22. On the shaft 22 at 42 is fixedly mounted a driving pinion 43 meshing with a follower 44 fixedly mounted on a transmitter shaft 45 revolvingly supported by bearings 48, 48 of pedestals 19, 19. A transmitting pinion 46 is mounted on the shaft 45 meshing with a driven gear 47 on the driven shaft 39.

On the trough 9 is mounted a bracket 49 provided with a collar 50 for 'the post 36 and with bearings 51 for the shaft 39. Above the collar 50, and on the post 36 is .revolubly mounted a sleeve 52. On the sleeve 52 is fixedly mounted a bevel gear 53 meshing with a mutilated gear 54 mounted on the driven shaft 39. The sleeve 52 is supported above the collar 50, by a collar 143, of sufficient length for causin the gear 53 mounted on the sleeve 52 to %B in the iroper position for meshing with the mutilated gear 54. On the shaft 39, at the hearing 51 is fixedly mounted a crank arm 55, carrying a pin 56 at a distance from the center of the shaft 39 to the farthest point on the circumference of the pin 56 equal to the distance from the center of the gear 54 to the top of its teeth for a slotted sliding bar 57. The slotted bar 57 consists of straight edges 58, 58 and 58, 58' jointed together as at 59 and 59, at a distance apart equal to the diameter of the pin 56. The edges 58, 58 are joined together by a curve 60 of a radius equal to the distance of the center of the pin from the axis of the crank plus the radius of the pin, and the edges 58 58' are similarly joined by a curve 60 equal and opposite to the curve 60.

On the chest 4 is mounted a bracket 67 provided with a bearing 68 for a rod 69. On rod 69 are mounted levers 70, 70 carrying counterbalaneing weights 71, 71, at 72, and joined by a rod 74 at 73. On the rod 74 and between the levers 70, 70, are pivoted the arms 75, 75 of a leak 76 whose arms 77, 77, are pivoted on a sleeve 78 slidingly mounted on the sleeve 52 which is free to revolve in the sleeve 78.

The arms 77 of the leak 76 are joined by a rod 79 on which is pivoted a head 80 mounted on the adjustable pin 65. The sliding bar 57 is mounted on a bar 81 free to slide in a guide 82 of a bracket 83 mounted on the socket 35 supporting the post 36. The sleeve 78 carries a tray 84 provided with mouths 85 over the lips 86 of cups 87 provided with holes 88 in their bottoms 89 for the brush spindles 32 to pass through them and through the tray 84. Above the tray sleeve 78 and over the revoluble sleeve 52 is mounted a sleeve 90,

supported by ball bearings 91 provided by the sleeve 78 and slidingly supported by a key 92, in a key way 93 of the sleeve 52. On the sleeve is fixedly mounted a spider 94 carrying trays 95 provided with months 96 for receiving the lips 97 of bottles 98.

On the spider 94 and above the sleeve 52 is mounted a sleeve 99 within which the sleeve 52 is free to revolve. The sleeve 99 is provided with an outside thread 100 and is also provided with handles 101, 101, by means of which it may be turned on the sleeve 90. On the sleeve 99 is mounted a collar 102 provided with an inner thread 103 engaging the outer thread 100 of the sleeve 99. section 104 is cut out of the collar 102 which is free to slide inwardly to cause its threads to wedge in the threads of the sleeve 99 for locking the collar 102 on the sleeve 99. The collar 102 is provided with a lug 105 provided with a threaded hole 106 for the threaded surface 107 of a bolt 108 carrying a head 109 on its outside and bearing against the section 104 at its threaded end. A plate 111, is pivoted on the collar 102 at 112. The plate 111, is provided with frames 113 having' holes 114 above holes 115 of the plate 111. Pins carrying disks 116 pass through the holes 114 and and have springs 117 coiled around them. The springs 117 are compressed between the plate 111 and the frames 113 resulting in the tendency of forcing the disks downwardly.

The lug 105 of the collar 102 is rigidly connected through an arm 118 with a sleeve 119 mounted on the post 36 and provided with a key 127 free to slide in a way 120 of the post 36. The sleeve 119 has a bracket 121 on which is pivoted a lever 122 whose arm 123 is free to swing in a slot 124. A bar 125 is pivotally connected between the plate 111 and an arm 126 of the lever 122. A bar 66 is mounted on the frames 113 which carries a weight 128 for holding down the plate 111. On the post 36 near its top 129 is mounted a collar 130 by a set screw 131 carrying a check pin 132.

On the trough 9 is mounted a bracket 133, supporting a trough 136 having a reservoir 134 over its bottom 135. On the reservoir 134 are tapped rinsers consisting of pipes provided wlth spouts 138. A water pipe 139 connects the reservoir 134 with a pipe 140 of a coupling 141 whose pipe 142 is connected through a pipe 10 with the reservoir 6. The coupling 141 is tapped on a main 145 supplied with water under pressure through a valve 146 controlled by a handle 147 operated by a lever 148 pivotally connecting t e handle 147 with one of the levers 70 at 73'. A drain pipe 149 connects the trough 136 with the trough 9 which is drained through a pipe 150.

Vertical rods 151, 151, support a platform 152 bolted on top of post 36. A motor not shown may be mounted on the platform 152, and be connected by a belt 154 with a loose pulley 153 mounted on the power shaft 22 to be shifted by a belt shifter 155 on to a tight pulley 156.

The bottles are supplied in crates 157 consisting of an upper frame 158 and a lower frame 159 joined by uprights 160 and are provided with supports for supporting vertlcally the bodies 162 of the bottles 98 and with collars 163 for the necks 164.

The machine as above described consists of sixteen vertical washers caused to revolve continuously in a horizontal plane, by the train of gears 31 driven by the large gear 30 mounted on the vertical shaft 27. The gear 30 meshes with the upper gear A and with the lower gear B thereby distributing the wear on the gear 30 more evenly. The gear A meshes with the gear C and the gear B meshes with the gear D, but A and B do not mesh, the wear is therefore more evenly distributed. Each of these gears drives a line of gears independently of the other and all danger of interference is thereby avoided.

The washers are supplied with water from the reservoir 6 through the nozzles 15 and this is discharged around the brushes 34: through the spouts 33. Directly over the washers are cups 87 arranged to move off and over the brushes for the purpose of pressing out the dirty water, which is caught by the trough 9 and discharged through the drain 150 thus preventing any of the water from being spilled around the machine. The cups are suspended from the tray 84, carried by the slidingly mounted sleeve 78. Above the sleeve 7 8 is mounted the sliding and revolving sleeve 90 carrying the trays supporting the bottles. As a tray with unwashed bottles is immediately over a cup tray, the sleeve of the cup tray is made to slide down taking along the sleeve of the crate tray and forcing the bottles over the brushes. As the washers rotate, the wet brushes wipe and loosen the dirt in the bottles.

It has been found from experience, that while the brushes may loosen the dirt, they would not take all the dirt along. And to rinse the dirt out, the tray carrying the bottles is lifted off the brushes, when the sleeve supporting the trays is made to turn until the tray of unwashed bottles is over the stationary rinsers, at the same time bringing another tray of unwashed bottles over the washers, and as the sleeve slides down, the washed bottles are over the rinsers and the dirt is rinsed out by the water forced through the rinser-spouts supplied by the reservoir 184, and to avoid the spilling of the water around the machine, I provide the draintrough for catching the water which is conveyed away by the drain pipe 149. The above arrangement results in the combination of two machines one for washing bottles and one for rinsing, and the only power consumed is that necessary to operate the washing machine.

The sleeve carrying the trays is loosely mounted above the sleeve carrying the on tray to slide up and down with it and as it is also to revolve past it, the cup tray sleeve is provided with ball bearings for reducing the friction.

The various mechanisms are driven from a single power shaft 22, and to avoid the loss of ower in transmission, the driven shaft 39 is mounted near the power shaft and is driven by means of the transmitter shaft 45. This arrangement results in reducing the strain on the driven shaft which might otherwise be caused by the variation in the speed of the power shaft as the brushes revolve in the bottles or are free.

The most important improvement which will be specially claimed consists in the construction, combination and the arrangement of the parts for cailsing the sleeves to either slide or revolve and to pass through various periodical movements and cycles. 1 The driven shaft 39 revolves in a vertical plane and transmits the motion to the revolving sleeve 52 by means of the mutilated gear 54 meshing with the gear 53 on the revoluble sleeve 52, and by means of the crank pin 56 operating the slotted bar 57 for causing the slidingly mounted sleeve to reciprocate in a vertical plane. The revolving sleeve 52 is to cause the bottle carrying trays to carry a set of unwashed bottles to a position over the washers and a set of washed bottles to a position over the rinsers, when it is to stop to permit of the bottles being forced down over the washers and rinsers, and as the rinsers are atright angles with the washers the trays must be made to revolve periodically through a quarter of a revolution to every revolution of the driven shaft. This is accomplished by making the mutilated gear of a truncated cone having only a limited number of teeth, to mesh with the teeth of the gear on the revoluble sleeve during one quarter of a revolution. I find it preferable for the sake of economy to make the time of transfer of bottles equal to one-fifth of a minute. The intermittent gear must therefore make five revolutions per minute giving a velocity ratio of three to two, and resulting in the toothed portion of the mutilated gear covering onesixth of the surface of the gear. In order to avoid jamming every time the teeth of the two gears become engaged, the gear 53, has every lasttooth of contact and its following first tooth of contact joined by an arc having a radius equal to that of the base circle or smooth surface of the mutilated gear. The sleeve 78, must be caused to slide upwardly to force the cups off the washers, and to take along the sleeve carrying the crate trays to lift the rinsed bottles off the rinsers, before the sleeve 52 begins to revolve, and to remain stationary during the quarterly revolution of the sleeve 52. The sleeve 78, is pivotally supported by the arm 76, on which the slotted bar 57, is pivoted, and the operation is therefore governed by the accuracy of the design of the slotted bar.

The sleeve 7 8 is caused to slide upwardly when the pin 56 is traveling along the straight edges 58, 58 to the left of the curved surfaces 60, 60', the direction of motion being fixed by the position of the rinsing mechanism. Just as soon as the first tooth of the intermittent gear comes in contact with a tooth of its follower, the sliding sleeves must have reached their highest points, to cause the bottles to clear the tops of the washers and of the rinsers, and for the slotted bar pin to be at the commencement of the curved surface 60, and it must then travel from left to right along said curved surface as the teeth of the intermittent gear mesh with the teeth of the follower causing the sleeve 52 to revolve, when the sleeve 78 is to remain stationary. The curved surface 60, must therefore be of a radius equal to the distance of the farthest point on the circumference of the pin from the center of its crank. This also fixes the position of the pin relative to the position of the teeth of the mutilated gear, 2'. 6., the center of the pin and the first point of contact of the first tooth of said gear must lie in the same plane, and the first point of contact of the first tooth of the intermittent gear with a tooth of its follower must be coincident with the first point of contact of the pin and of the curved surface 60. As soon as the sleeve 52 revolved through a quarter of a revolution, a tray of inverted bottles is directly above the washers, and a tray of washed bottles directly above the rinsers. This determines the position of the last point of contact of the last tooth of the intermittent gear and the end of the curved surface 60. The angle subtended by this curve must therefore be equal to the angle subtended by the toothed surface of the 1ntermittent gear. The pin then travels along the edges 58, 58, to the right of the curved surfaces causing the sliding sleeves to descend. This is followed by the pin traveling along the surface 60' similar in every respect to the surface 60, during which both the revolving and sliding sleeves remain stationary, thus completing the cycle of operations. As all these movements must be exact, the operatin pin 56 is guided along the inner surface the slotted bar 57, by a guiding pin 61, traveling on the outside of the slotted bar, and to allow for errors the pin crank is provided with a slot 62 along which the pins are clamped.

To simplify the operation it is best that the operating pin and the slotted bar travel in the same plane, the bar is therefore mounted on the vertical bar 81 constrained to slide in a vertical plane by the guide 82, and for preventing any unnecessary strain on the slotted bar it is provided with a supporting brace 63.

The washers and rinsers are supplied with water from their respective reservoirs through their respective feed pipes branching out from the supply pipe controlled by a valve. To provide for the sufficient supply of water necessary for the thorough washing and rinsing of the bottles without unnecessary waste of water, it is preferable that the supply be cut off at the moment the bottles leave the washers and rinsers, and to be opened the moment the bottles begin to slide over the washers and rinsers. This is accomplished by the lever connecting the valve with one of the weight levers, which, by the aid of the weights they carry, are caused to rock in unison with the arm 76, pivotally supporting the sleeve 78, and on which the head 80 of the slotted bar is pivoted.

To avoid any strain on the bar 57 which may be due to some imperfections or wear in the levers, connecting arm or sleeve, the head 80 can be adjusted by means of a threaded pin 65 in the socket 64.

The washer brushes are made to fit closely in the bottles, and to guard against the brushes lifting the bottles out of the mouths of the tray, I provide the disks 116 which are actuated by the springs to press against the bottoms of the bottles and carried by the plate 111 pivoted on the collar 102 and provided with a bar carrying a weight to se cure the parallelism of the disks with the bottoms of the bottles.

To provide for the accommodation of longer or shorter bottles, I mount the plate supporting collar 102 adjustably on the slidingly mounted sleeve 99. The collar 102 has an inner thread 103 engaging with the outer thread 100 of the sleeve 99. The sleeve 99 is provided with handles 101 by means of which it can be turned for causing the collar to travel up or down to lengthen or to shorten the distance between the crate carrying tray and the disk plate. For locking the collar on the sleeve the collar 102 is provided with a recess 103 for a block 104 which can be forced by the thumb-nut 109 tomove inwardly in said recess for wedgin g it in the threads of the sleeve.

The plate collar 102 is rigidly connected with the slidingly mounted sleeve 119 provided with the platform 121 on which is pivoted the lever 122. The check collar 131 is mounted on the post 36, so that when the sleeve 78 is caused to slide upwardly causing the sleeves 90, 99, 119 to slide upwardly until the bottles are off the brushes, the

arm 123 of the lever 122 is forced against the check bolt 132 causing it to rock in the recess 124. The disk plate being pivotally connected with the lever 122 by the arm 125 is lifted upwardly, releasing the bottles at the moment the crate trays commence to move away from the washers.

The post 36 is securely held in its vertical position by the top 152 joining it with the two uprights 151, and could be utilized as a base for a motor or for any other source for supplying the power to the machine and to be belt connected with the loose pulley 153.

To start the machine it is only necessary to throw the belt 154, on to the tight pulley 156 for driving the main power shaft 22. As soon as this is done the machine operates automatically and just as long as a crate of washed bottles is removed and at the same time a crate of unwashed bottles is mounted on the crate trays, so as not to allow said trays to run idle, the machine continues to wash and to rinse bottles, preferably in sets of sixteen, until the belt is shifted from the tight pulley. The power shaft drives both the vertical and horizontal transmitter shafts. The vertical transmitter shaft causes the washers to spin continuously, while the horizontal transmitter shaft drives the shaft carrying the intermittent gear and the crank with the operating pin. The intermittent gear causes the follower to revolve periodically, and the pin causes the slotted bar to move with a periodic reciprocating motion in vertical planes. The mutilated gear meshing with the follower on the revoluble sleeve converts this motion into a periodic rotation in a horizontal plane, and as the crate carrying trays are supported by a sleeve constrained to revolve with the gear sleeve, crates of bottles are periodically carried to the washers and rinsers. The crank pin acting on the slotted bar converts the unlform rotary motion of the crank in a vertical lane, into a pcriodic, reciprocating motlon of the slotted bar in a similar plane which consists of an up-stroke corresponding to one-third of the period of rest 0 the follower of the mutilated gear, followed by a period of rest corresponding with the period of motion of the follower-gear followed by a downstroke corresponding to a further one-third period of rest of the follower, followed by a period of rest corresponding to one-sixth of the period of rest of the follower thus completlng a c cle. During the up-stroke of the slotted ar the sleeve carrying the cup tray is forced to slide upwardly, forcing the bottles off the washers and rinsers, and forcing the cups over the brushes, at the same time causmg the valve operating lever to bring the valve to a position for quickly cutting off the water from the washers and rinsers. The check bolt then causes the disks to release the bottles, and the crate carrying trays begin to revolve past the cup tray, until a tray with a crate of unwashed bottles is over the washers and a tray with a crate of washed bottles is over the rinsers, when the crate tray sleeve is stopped, and the cup tray sleeve commences to slide down. The check bolt then releases the disk plate, and the crate carrying trays slide down, the weight of the disk plate forcing the disks against the bottoms of the unwashed bottles, forcing them over the brushes, and the washed bottles are slid over the rinsers. The valve meanwhile opened, results in the washed bottles commencing to be rinsed and the unwashed bottles to be wiped by the wetted brushes, when all the sleeves stop allowin the bottles to be thoroughly washed and rinsed, when the cycle is completed by the upstroke of the cup tray sleeve.
